matlab解方程~为什么解不出来 求助大神~~~

图片是我想用matlab解得方程组，a b o 是三个未知数请教大神是哪里出了问题?不胜感激! syms a b o [a,b,o]=solve('o+(a-o)*gamma(1+1/b)=30','exp(-((30.5-o)/(a-o))^b)=0.5','((a-o)^2*(gamma(1+1/b))^2)=0.017)'); ??? Error using ==> solve>getEqns at 178 ' ((a-o)^2*(gamma(1+1/b))^2)=0.017) ' is not a valid expression or equation.Error in ==> solve at 67 [eqns,vars] = getEqns(varargin{:});

Answer 1

你第三个方程输入错误了啊!
是这样的:
syms
a
b
o
[a,b,o]=solve('o+(a-o)*gamma(1+1/b)=30','exp(-((30.5-o)/(a-o))^b)=0.5','(a-o)^2*(gamma(1+2/b)-gamma(1+1/b)^2)
=
0.017^2');
